IMPROVEMENT IN GRATE-FRAMES.

Specification forming part of Letters Patent No. 158,472, dated January 5, 1875; vapplication led September 5, 1874.

To all whom it may concern Be it known that I, HoRATIo M. CREAMER, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Grate-Frames, of which the following is a specification:

Heretoi'ore the ornamental frames surrounding hre-places or grates have been, so far as I am aware, cast in one piece, and, consequently, a separate pattern was required for each sized tire-place or grate.

The object of my invention is to produce a grate-frame that shall, within certain limits, be adjustable or variable as to height or width, or as to both height and Width at the same time, and shall be, when in position, undistinguishable in external appearance from a grate formed in the ordinary way.

My invention consists in a grate-frame, the body of which is cast in two pieces, and which is provided with separate pedestals and a separate centerpiece, hereinafter more fully described, by which the height and width of the whole may be to a cert-ain extent adjusted or varied to suit the lire-place or the size of the grate to or Vin connection with which it may be desired to apply the same.

The following is a description of my inven'- tion, reference being had to the accompanying drawing, in which similar letters indicate corresponding parts in the several gures.

Figure l is a front, and Fig. 2 a back, view view of my adjustable or variable grateI'ra-me in position. Fig. 3 is a vertical section in the line w w, Fig. 2. Fig. 4 is a section of a pedestal as attached, taken in the line z z, Fig. 2. A and B are the main side pieces of the grate-frame, and may be cast in any suitable ornamental form. l) is a center-piece, also cast in any suitable ornamental form, and having made fast to the back thereof the threaded bolt j'. The pieces A B also have made fast to the backs thereofthe threaded bolts g g, and have, morever, near the bottom, the holes or slots h h. I I are pedestals, the backs of which are fitted to the fronts of A B, and to the backs of these pedestals are suitably made fast the threaded bolts 7c k. E and L are clamping-plates, of a form suitable to lit against the backs of A and B, and provided with holes `or slots for the bolts g g and f. By means of nuts upon the ends of the bolts g g, j', and k k, the parts are held rigidly together, as shown, and may be adjusted in width to the limit of the center-piece D, and in height to the limit ot' the pedestals I I.

The invention is applicable to grate-frames of square or other form, as well asI to those of the arched forni represented. Its advantages are that the manufacturer will require a smaller number of patterns `to make grate-frames ot' a given number of sizes, and the dealer will not require so large a stock to meet the demand for tire-places of diiferent sizes.

I claiml. The side pieces A and B of the grate frame, in combination with the adjustable center-piece D, ijtting between the upper ends of the side pieces ot' the grate-frame, whereby the latter may be adjusted in width, as herein shown and described. a

2. The combination, with the side pieces A and B of the grate-frame, 'of the vertically-ad justable pedestals on the lower ends of the side pieces for adjusting the same in height, substantially as and for the object specied.

3. An adjustable or variable grate-frame, consisting of two separate pieces constructed to join at the top and center, two separate pedestals, a separate center-piece, and means of uniting them, combined substantially as herein described.
